Applioation filed September 3. 1907. Serial H01 39L158.

To all'whmh it WCOMGM: Be it known'that'LOwnn E. CASEY, of

- Naslm'a,- in 'the countyolf Wilkin andState embodying m of Minnesota, have invented certain new and useful Improvements in Ditching and Grading Machines and I do hereby declare the following to be a full, clear-,'and exact description of the-invention, such as 'will enable others skilledin the art towhich it ap-' construct a machine of the character specified that, as the machine travels forward, the

dirt will be. taken from=.the roadway and thrown laterally so as to be deposited in'the .center of the roadwa or, when constructing "a ditch, so that the irt will be thrown later:

ally from the machine and scattered over the ground some distance from thedit'ch under onstruction. a

With this objectin' 'view the invention consists in certain novel features of.construc'- tion and combinations and arrange'mentof' parts as hereinafter set forth and pointed out intheclaims. l p

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a machine improvements. Fig. 21is a plan view.

Fig.4) has a general conical form and comprises, a series. of blades 10 secured at their forward ends to the shaft 7 and the rearends of said blades (which are wider than their forward ends)- are-comnected brace-rods 11 and. thelatter are also secured to theshafti7 lever 12 is mountednpon-thejframe and the short arm 13 of this lever is connected, through'i the mediumof a ro 1 h the rearend filth-5e:

When the machine 'isused in grading a road however, itis desirable that the dirt shall'be so thrown as to be concentrated in the center oftheroadway. For this reason I provide a guard 28 pivotally connectedor hinged to a sultahle support on theframe-work and provided with an arm 29 which is connected, by means ofa rod 30 with a lever 3l-1and the latteris provided with a latch "32 to en age a toothed-segment 33. By means 0 this guard the dirt will bed'p'revented from'bemg thrown broadcast an caused. to fall upon the roadway a compare}. tively short distance laterally from themachine. The distance which the dirt will be thrown can be regulated by adjusting the angle of the guard.

This lever is with a beveled gear 20 which receives mo-- tion from a similar, gear 21.on a shaft 22 The shaft 22 is also provided with a. sprocket- 1 '80 will be provided with a pulley 26, .to receive Asftheinachine} moves forward, i

The construction shown in Fig. 5 com risesa shaft 34 similar in all res ects tothe s aft' 7 and will be attached to th ling in the samefmanner in which said shaft 7 is shown attached in Fig. 2. This dirtthrower also has a generalconical form but instead of em loying. flat-blades as shown in Fig. 4, sever'aFseries of fingers 35 are secured to the shaft 34 :and the outer end of each finger is pointed so that when the device is rapidlyrotated it will loosen the soil and also throw the same laterally.

Various sli ht changes might be made in for rapidly rotating said dirt-thrower axially to cause it. to throw dirti-n a'direction laterally from the machine.

2. In amachine of the character described, the combination with a traveling frame, of a dirt-thrower, means for rapidly rotating said dirt-thrower, and an ad ustable guard to direct the dirt thrown laterally by the dirt-' thrower.

3. In a machine of the character described, the combination with a traveling frame, of a dirt-thrower mounted thereon and ada ted to discharge dirt laterally from the mac he, means for adjusting the dirt-thrower vertically, and means for rapidly rotating said dirt-thrower;

4. In a machine of the character described, the combination with a traveling frame, of a e' universal coupcreme dirt-thrower mounted thereon and ada ted' to discharge dirt laterally from the mac 'ne,

meansv for moving the dirt-thrower downwardly in contact with the ground, means for adjusting said dirt-thrower laterally, and

driving means for the dirt thrower.

' 5. In a machine of the character described,

the combination with a traveling frame, of a dirtthrower having a general conical form and comprising a series of devices to 0 age the soil and throw the same laterally rom the machine, and means for rapidly rotating said.dirt-thrower. I

.6. In a'machine of the character described, the combination with a traveling frame,'a shaft mounted thereon and means for rotating said shaft, of a dirt-thrower connected with and trailing behind said shaft. 7. In a machine of the character described,

shaft mounted thereon and means for rotatingsaid shaft, of a dirt-thrower havin a the combination with a traveling frame, a'

general conical form and provided wit a shaft connected with and rotated by said first mentioned shaft.

8. In a machine of the character described, the combination with a traveling frame, a

shaft mounted thereon and means for rotating said shaft, of a dirt-thrower provided with a shaft, a universal coupling connecting said shaft, and levers connected with the rear end of the dirt-thrower shaft for adjusting the dirt-thrower vertically and laterally. 9. In a machine of the character described, the combination with a traveling frame, a dirt-thrower adapted to throw dirt laterally from the machine and means for rotati said'dirt-thrower, of aguard having-a hing dd connection with the frame of the machine,

- anarm projecting from said guard, a lever,

a connection between said arm and lever,

and means for locking the lever to secure the guard at any desired angle.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
